Add "ipstatistics"-plugin. This plugin parses "/proc/net/netstat" and
"/proc/net/snmp6" to get the overall ipv4 and ipv6 usage.

In IPv4 the default route can be written as
0.0.0.0/0
In IPv6 the default route can be written as
::/0
If u try
owipcalc 0.0.0.0/0 contains 1.1.1.1
or
owipcalc ::/0 contains ::1
owipcalc will respond with 0 meaning that the "default prefixes" do not
contain the routes.
That is why we check now for 0 prefix.
Furthermore, if the prefix is 0, i will be 16. We will access a negative
array entry in the line:
uint8_t net1 = x->s6_addr[15-i] & m;
Divide by % 16 to prevent i becoming 16:
uint8_t i = ((128 - a->prefix) / 8) % 16;

Count the current dhcpleases. Currently, we use a bash script
that does the same job (Freifunk Berlin). We want to use native
collectd plugin for that.

If you want statistics about IPv6 you can use snmpv6 exporter.
Currently, the "/proc/net/snmp6" is existing but all values are
just "0".
To use this plugin you have to set
CONFIG_PROC_STRIPPED=n
I will find a way to enable the important ipv6 statistics by default.

Fix "hostapd_ubus_stations.lua". The bit-lib that is imported and the
one specified as the dependency do not match. Use luabitop.
Signed-off-by: Nick Hainke <vincent@systemli.org>
There is already the hostapd_stations exporter, which uses
hostapd-utils (more precisely hostapd-cli) to get client statistics.
However, the ubus interface is permanently integrated under hostapd
in OpenWrt. So this exporter needs one dependency less.
For now it exports mainly the rrm statistics. Many people are
interested in what your device supports. The exporter provides
information about the radio-resource-managment extensions.

Includes:
- dawn_uci: fix crashing when uci config is received
- tcpsocket: add option to add server ip
A new config option allows to add a server ip
option server_ip '10.0.0.2'
However, this server does not send anything back. Therefore it is not
possible to change the node configuration. This will probably be added
soon. The main goal of this commit is to allow monitoring of all nodes
in a network with DAWN, e.g. clients, channel utilization, ...
Also a network option (3) has been added which allows to use TCP but
not to announce your daemon in the broadcast domain. This allows you to
create a monitor-only node that holds only the local information and
forwards it to the central server.
A monitor-only node could be configured like
option server_ip '10.0.0.1'
option tcp_port '1026'
option network_option '3'
Another possible config is
option server_ip '10.0.0.1'
option tcp_port '1026'
option network_option '2'
Here, the node shares information with a central server, which can be
located outside the broadcast domain. Nevertheless, it also shares
information within its broadcast domain and can therefore perform
client steering.

If set_hostapd_nr config flag is set, dawn will insert the nr reports
to allow the hostapd to answer to nr requests from clients.
Improve the synchronization of rcpi and rsni in the network.
Further, clients with bad 802.11k were sending beacon reports with
bssid 00:00:00:00:00:00. Catch those corner cases.

Dawn is a decentralized WiFi controller.
Just install dawn and the APs will find each other via umdns.
They periodically exchange information about connected clients, wireless
statistics and other needed information. With that, the daemon load
balances clients between different APs through association control.
Further, the daemon exposes through ubus the hearing map and the
complete wireless network overview. The hearing map is the list of all
probe requests seen from a client from all APs that are running the
controller.
Hearing map:
ubus call dawn get_hearing_map
Network overview:
ubus call dawn get_network
Dawn has a graphical user interface called luci-app-dawn. With that, the
load balancing and other useful settings can be controlled.
